3 - INSTALLATION
MECHANICAL MOUNTING: The instrument, in DIN case 48 x 96 mm,
is designed for panel mounting. Make an hole 45 x 92 mm and insert the
instrument, fixing it with the provided special brackets . We recommend to
mount the gasket to obtain an IP 54 front protection. Avoid to place the
instrument in areas with humidity or dirt. Connect the instrument as far as
possible from source of electromagnetic disturbances so as motors, power
relays, relays, electrovalves,etc. The instrument is removable from its
housing by the front side : is recommended to disconnect the power supply
from the instrument when is necessary to do this operation.
ELECTRICAL CONNECTIONS: Carry out the electrical wiring
connecting only one wire for each terminal , according to the following
diagram, check that the power supply is the same as indicated on the
instrument and the loads current is not upper than the maximum current
admitted. The instrument, being a built in equipment with permanent
connection into a cabinet, is not furnished with internal device protecting
from overcurrent : it's recommended , therefore, to properly protect all the
electric circuits connected to the instrument, with devices (ex. fuses)
proportionate to the circulating currents. It's strongly recommended to use
cables with proper insulation, according to the working voltages and
temperatures. Furthermore, the input cable of the probe has to be kept
separate from line voltage wiring. If the input cable of the probe is
screened, it has to be connected on the ground with only one side. It is
advisable to check that the parameters are those desired before connecting
the outputs to the actuators so as to avoid malfunctioning . Whenever a
failure of the instrument could cause dangerous or damaging situations, it
should be kept in mind that the plant has to be provided with additional
devices to ensure the safety.
4 - OPERATING MODE
4.1 - ON/OFF CONTROL (C1)
The ON/OFF control mode acts setting parameter "Con1" = "OnOF" and
works on C1 output depending on the set point ("SEtP"), on the functioning
mode ("FunC") and on the hysteresis ("HSEt") programmed.
The instruments proceed with a ON/OFF regulation mode, with symmetric
hysteresis. The regulator, therefore, behave in the following mode : in case
of inverse action or heating mode ("HEAt"), deactivates C1 output when
the temperature reaches the value [SEtP + HSEt] and than actives it again
when temperature goes under the value [SEtP - HSEt] ; on the contrary, in
case of direct action or cooling mode ("CooL"), deactivates C1 output
when the temperature reaches the value [SEtP - HSEt] and than actives it
again when temperature goes upper than the value [SEtP + HSEt].
4.2 - SINGLE ACTION PID CONTROL (C1)
The PID single action regulation mode acts setting parameter "Con1" =
"Pid" and works on C1 output depending on the set point ("SEtP"), on the
functioning mode ("FunC") and on the control algorithm programmed.
